1 <br />TRAPPER MINING INC. <br />III IIIIIIIIIIIIIIII <br />it <br />Q~ `~ <br />April 23, 1998 <br />RECEIVED <br />APR 2 7 1998 <br />Mr. Tom Kaldenbach <br />Environmental Protection Specialist <br />Colorado Division of Minerals and Geology <br />] 313 Sherman Street, Room 215 <br />Denver, Colorado 80203 <br />Dear Tom: <br />Division of Minerals 8 Geology <br />12E: Trapper Mine First Quarter 1998 Sediment Pond Inspections <br />hnpoundment inspection results for the first quarter of 1998 are enclosed. The <br />inspections were performed by qualitied inspectors under my direction. <br />The inspections were performed from mid-February through the first part of March. The <br />required maintenance items noted during the quarterly inspections are not significant with <br />regard to the ponds' structural integrity. As you are aware, the northwest region of <br />Colorado experienced unusually warm temperatures the week of March 23, 1998. This <br />resulted in rapid snow melt causing notable flooding in and around Craig. Several of <br />Trapper's ponds suffered minor damage as a result of the runoff. However, the damage is <br />not threatening the structural integrity of any of the ponds, and all the ponds are <br />functioning as designed. All required maintenance items are scheduled to be initiated as <br />soon as the weather permits. <br />Please call if you have any questions or need additional information. <br />Since~r-ely~, o~Q <br />~~ 0 <br />Raymond G.
